Episode Title:
Connection / Friends.
Episode Description:
Connection: While exploring the submarine, the girls inadvertently synchronize their camera to the submarine's computer and it displays their photographs, plus those Kanazawa took before giving them the camera. Among the computer files, they find videos of people and past events, including the war which led to the destruction of humanity. Later, a larger Nuko resembling the pillars they encountered earlier, suddenly appears and swallows Yuuri. Chito pursues the creature outside the submarine and finds Yuuri safe as the creature had only wanted to ingest her radio...
Friends: With the submarine now completely shut down, Chito and Yuuri continue their journey towards the top level of the city, with a new sense of camaraderie and their importance to each other.
